A methodology for assessing MIT's energy used and greenhouse gas emissions

(cont.) actions can be made to decrease losses and therefore increase plant efficiencies. As production efficiencies are maximized, fuel use and thus emissions are minimized. From fiscal year 1998 to 2003, the gas turbine efficiency, based on the higher heating value, remained approximately constant at 24%. The heat recovery steam generator effectiveness has decreased 11% from 42.1% to 37.4%. It has been shown that the decrease in the heat recovery steam generator's performance can be attributed to fouling effects on the heat transfer surfaces between the hot exhaust gasses and the water stream. An accurate inventory of MIT's greenhouse gas emissions is a necessary first step in reducing these emissions. This assessment identifies areas with the greatest potential for reducing utility related emissions. This inventory will also allow MIT to continue to evaluate its greenhouse gas emission trends and thus contribute to the emission reduction target the city of Cambridge has created.
